Abstract

A fuel vapor feed controlling apparatus is provided for a lean burn internal combustion engine for suppressing a rich misfire or a surge when the fuel vapor is fed into the lean burn internal combustion engine. A purge controlling unit controls a fuel vapor amount to be fed from a fuel reservoir to the internal combustion engine in response to an operational condition of the internal combustion engine. A first compensation unit compensates for the fuel vapor amount so that an engine revolution speed of the internal combustion engine may be identical with a target revolution speed. The purge control unit performs a purge control on the basis of a compensation value compensated by the first compensation unit. An air/fuel ratio judging unit judges a shift from an air/fuel ratio corresponding to a lean burn to an air/fuel ratio that is richer than the former air/fuel ratio in the lean burn operation. A fuel restricting unit restricts at least a purge amount out of the purge amount of fuel vapor determined by the purge control unit and a fuel amount to be injected from a fuel injection valve of the internal combustion engine when the air/fuel ratio judging unit judges that the air/fuel ratio is to be enriched. A fuel vapor compensation unit compensates the fuel vapor on the basis of the operational condition of the internal combustion engine. An injection amount changing unit changes the fuel injection amount to the internal combustion engine on the basis of the compensated fuel vapor amount. A correction controlling unit increases and decreases the fuel vapor amount in response to the operational condition after the injection amount change and controls a fuel injection timing on an advance side or on a retard side.
